Conversion of nitroarenes to aminoarenes has attracted great attention in pharmaceutical industry, agricultural production, environmental protection and chemical catalysis area. In this work, ficin capped gold nanoclusters(ficin@AuNCs) were prepared for the reduction of 4-nitrophenol to 4-aminophenol.The...
Surprisingly, such small distinctions in the structure cause a 16-fold catalytic activity leap in the catalytic reduction of 4-nitrophenol to 4-aminophenol... B Yan,X You,X Tang,... - 《Chemistry of Materials A Publication of the American Chemistry Society》 被引量: 0发表: 2024年 Facile...
Preformed Au colloidal nanoparticles immobilised on NiO as highly efficient heterogeneous catalysts for reduction of 4-nitrophenol to 4-aminophenolA facile approach to synthesise highly active and stable Au/NiO catalysts for the hydrogenation of nitro-aromatics is reported. Preformed gold nanoparticles have...
The catalytic activity of the Pt/α-MnO2 nanorods was tested in the catalytic reduction of 4-nitrophenol to 4-aminophenol. MP1, with the lowest platinum content, exhibited the highest mass normalized rate constant kapp/mPt of 1.8 × 104 s−1 g−1. The study suggests that the presence ...
from α-MnO2to Mn5O8.XPS showed a decrease in Pt(IV) and Pt(II) with Pt loading, while Pt(0) increased.Pt/MnO2nanorods displayed excellent catalytic activity for 4-NP to 4-AP reduction.The presence of Pt(IV) is not a limiting factor for the catalytic conversion of 4-NP to 4-AP...
The quantum yield of the nanoclusters was about 2.5% calibrated by rhodamine 6G. The catalytic activity of GSH-AuNCs was explored on reduction reaction of 4-nitrophenol to 4-aminophenol. The results showed a non-pseudo-first-order kinetics with 3 values of the normalized rate constant (i.e. ...
The resultant composite membranes were applied as the new catalytic materials for reduction of 4-nitrophenol to 4-aminophenol under room temperature. The new catalytic membranes exhibited the significant advantages, such as low dosage, high catalytic activity, easy recycling, and excellent stability....
The newly synthesized materials are tested as catalysts in the photocatalytic reduction of 4-nitrophenol to 4-aminophenol using Na2SO3 as hole scavengers, under UV light irradiation. ZnS–Bipy hybrid organic–inorganic materials show a high performance in the photocatalytic activity. In contrast, for ...
Cd/Ce/RGO was employed as catalysts in two different reactions: the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) and the oxidation of olefins. The results of the reduction reaction showed that 98 % of 4-NP was decreased in the presence of Cd/Ce/RGO (Cd to Ce 3:1 (...
The as-synthesized Ag/N-C nanocomposite with high specific surface area (875.2 m(2) g(-1)) and highly dispersed AgNPs exhibited adsorption properties and excellent catalytic activities for catalytic reduction of ecotoxic 4-nitrophenol (4-NP) to 4-Aminophenol (4-AP) under visible light. The ...
